Embodiment 1

[0038] A method suitable for synchronous ecological restoration of river banks in mountainous river towns, including the following measures:

[0039] A) Build a wetland purification system to purify the pollution entering the river and create a patchy landscape: build a wetland purification system on the riverbed with mixed discharge outlets for rain and sewage entering the river and rainwater outlets for entering the river. The wetland purification system is used to intercept and purify the pollution entering the river , The wetland purification system includes an interception pool and a wetland body. The interception pool is set upstream of the wetland body, and wetland plants are planted on the wetland body; the wetland body is composed of ecological gabions stacked in layers, and the wetland body includes the upper ecological gabion from top to bottom. 1. The middle ecological gabion and the lower ecological gabion. The upper ecological gabion is filled with ecological matr...

Abstract

The invention relates to the field of water pollution government and body ecological repair and discloses a synchronous ecological repair method suitable for a water front of an urban river segment ofa mountainous river. The method comprises the following steps: A) constructing a wetland purification system; B) constructing an ecological permeable dike to control and guide and purify water quality; C) repairing biodiversity of a riverbed with a flat basement; and D) ecologically remolding a hard embankment. The method can improve the water environment carrying capacity and the water ecological carrying capacity of the river obviously and also can create a green gallery with a good landscape. The method of ecologically repairing the water front of the urban river segment of the mountainousriver can improve the habitat heterogeneity, the biodiversity and the landscape diversity of the urban river segment of the mountainous river and improve the water environment carrying capacity and the water ecological carrying capacity of the river so as to quickly construct and repair the ecological system of the urban river segment of the mountainous river better.

Description

technical field [0001] The invention relates to the fields of water pollution control and water body ecological restoration, in particular to a method suitable for synchronous ecological restoration of water banks in urban river sections of mountainous rivers. Background technique [0002] Rivers are an important part of freshwater ecosystems and basin water systems. In addition to their water conservancy functions such as flood drainage, water supply, water transportation, and power generation, rivers also have ecological functions such as pollution purification, biodiversity protection, microclimate improvement, and supply of ecological products. However, along with the rapid development of urbanization and social economy, especially in industry and agriculture, problems such as damage to river habitats, ecological degradation, and decline in water environment carrying capacity have appeared in many areas of my country, and the ecological functions of rivers have also been a...
